To all whom it may concern Be it known that I,

- Keyed upon and rotatable with the driven shaft 2, 1s a sleeve 8, which has formed therewith, a dlsk or rim 9, which with the peripheral flange 10 constitutes the clutch drum of the shaft 2.

Upon one end of the sleeve 11, which. is keyed to the shaft 1, is carried a. disk 13, the dlsk 13 having disposed therein at-diametrically opposite points the guide rod or pins 14:, which are disposed within the sleeve 15 and for sliding movement to have their mnerends cooperate at the proper time with the studs 16 held in place by the nuts 17, and carried by the disk 9.

Upon the opposite face of the disk 13 are provided the two recesses 18, the shape of which is clearly illustrated in Fig. 5, and disposed for sliding movement within the respective recesses 18 are the two plates 19, one of which carries upon its outer end the segmental friction or clutch plate 20, each as clearly shown in Figs.

riphery of the drum 10 when the plates 19 are projecting to member carried by the driving shaft 1 to the clutch member of the driven shaft 2. Each of the arms 19 are provided with the apertures 21 through which is disposed the rounded head 22 of the actuating lever 23. Each of these levers, as clearly shown in Fig. 1, is disposed between the fixed and spaced lugs 24, of the sleeve 11 adjacent the disk 13 and upon each side of the elongated slot 17 and adjustably connected therein is the adjusting pin or screw 25, whose inner end is disposed to ride within the rounded recess 26 formed upon the sleeve 11, which provides a rocking fulcrum for the lever 23 to retract and project the plate 20, as will presently appear. The screw 25 is provided with the wrench receiving end 27, whereby the'screw may be adjusted to regulate the tension and action of the plates 19 and 20 and consequently upon the drum 10.

The clutch actuating drum 28 is mounted for sliding movement upon the sleeve 11.

A yoke 30 of usual structure is provided for moving the clutch member 28 to and in the flange or mm 31 of the member 28 are the two guide pins 14: which prevent the rotation of the member 28 independently of the disk 13.

plate being disposed to engage the inner pethus connect the clutch i the gripping effect thereof from the disk 13, while secured fixedly with- From the foregoing description, taken in connection with the drawings, the operation of the present invention is readily understood, but briefly stated it is as follows:

Assuming the member 28 is moved with its casing to the right as shown in Fig. 1, and the member 28 has actuated the lever 23 so as to retract the plates 19 and it is desired to connect the clutch member 28 through the yoke 30, the member 28 is moved to the left so that the free end 34 of the levers 23 will slide inwardly upon the inclined face 32 and thus gradually project the plates 20 into engagement with the drum 10 of the driven shaft carrying member 9. This action connects the clutch member so that the driving shaft rotates the driven shaft.

A continued movement of the member 28, which brings the end 34 of the lever 23 into the cylindrical socket 33, the member 28 being moved sutliciently forward to cause the pins 14 to be moved to have their free ends placed in the path to engage the studs 16. Thus the pins 14 and studs 16 are circumferentially alined and should there he a slight sliding engagement at the plates 20, such pins and studs abutting will hold the plates against further sliding and the shafts will be rotated in unison.

If so desired, the recess 33 may be pro- Vided so that the arms 33 will be slightly released when the bar 4 has been forced over, so that the levers 23 will release the clutch plate 20 and thus disconnect the same from the drum 10 so that no pressure is exerted at this point and the friction at this point is reduced when the shafts l and 2 are directly connected. This structure is illustrated in Fig. 6.

l/Vhat is claimed is: 1. A clutch, including two shafts disposed in axial alinement, a drum constituting one clutch member keyed upon and rotatable with one shaft, a sleeve having a disk keyed upon and rotatable with the second shaft, a plurality of radially disposed clutch members carried by said disk for engagement with the clutch member of the first shaft, levers carried by the sleeve, a sliding lever actuating member carried by the sleeve, said levers being connected to the sleeve by an adjustable connection whereby the gripping action of the members may be regulated, and cotiperable means carried by both clutch members and operably connected to the sliding lever actuating member for directly c011- necting the shafts.

2. A clutch, including two shafts disposed inaxial alinement, a drum constituting one clutch member keyed upon and rotatable with one shaft, a sleeve having a disk keyed upon and rotatable With the second shaft, a plurality of radially disposed clutch members carried by said disk for engagement with the clutch member of the first shaft, levers carried by the sleeve, a sliding lever actuating member carried by the sleeve, said levers being connected to the sleeve by an adjustable connection whereby the gripping action of the member may be regulated, and

coiiperable means carried by the drum and disk and operably connected to the sliding lever actuating member for directly connecting the shafts after the lever actuating member has been actuated to its full extent.

3. A clutch, including two shafts disposed in axial alinement, a drum constituting one clutch member keyed upon and rotatable with one shaft, a sleeve having a disk ke ed upon and rotatable with the second shaft, a plurality of radially disposed clutch 1nem-- hers carried by said disk for engagement With the clutch member of the first shaft, a plurality of levers, one lever to each clutch member carried by the sleeve, a sliding lever actuating member carried by the sleeve, each lever being connected intermediate of its ends to the sleeve by an adjustable conuection whereby the gripping action of the clutch members may be regulated, the lever actuating member having a socket for receiving one end of each lever, said socket having an inclined wall terminating in a reduced cylindrical end for engaging the ends of the levers to operate said levers, and cooper-able means carried by the drum and disk and operably connected to the lever actuating member to connect the shafts directly, said means cooperating when the ends of the levers are projected into drical end of the socket.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
